DN600–1000–500 Variable-Diameter Steel Pipeline Rehabilitation
Location: Site in Guangzhou, China
Asset: DN600 / DN1000 / DN500 continuous variable diameter steel pipeline
Key Challenges
- Continuous changing diameters increase rehabilitation alignment and construction difficulty.
- Adjacent to finished clean water tanks, requiring zero pollution risk during construction.
- Partially covered by existing structures, creating clustered hard to access leakage points.
- Located in a dense commercial area with restricted working hours and narrow access.
- Significant deviations between archived drawings and actual buried pipeline routes and conditions.
